View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Texas A&M Repository CHEMOPROTECTIVE EFFECTS OF FLAXSEED LIGNANS ENTERODIOL AND ENTEROLACTONE IN NON-TRANSFORMED COLONOCYTES A Thesis by CHRISTINA ALISON CURRY Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Clinton Allred Committee Members, Joseph Awika Jenna Anding Head of Department, Boon Chew December 2015 Major Subject: Nutrition Copyright 2015 Christina Alison Curry ABSTRACT Previous epidemiological studies have shown that colon cancer incidence is correlated to diet and estrogen status. Phytoestrogens are molecules with similar structures to estrogen that occur naturally in plants. There is in vitro and in vivo evidence that phytoestrogens in the diet can inhibit carcinogenesis. The phytoestrogenic mammalian lignans enterolactone (EL) and enterodiol (ED) in flaxseed have been shown to be effective in decreasing tumor incidence in carcinogenic models, but there is little data regarding their effects in non-malignant cells. The following studies used a non- transformed cell line of young adult mouse colonocytes (YAMC) to determine the protective effects of ED and EL in chemoprevention. Our results demonstrate that low levels of EL (1µM) and ED (5µM) are effective at significantly reducing cell growth and increasing apoptosis. These treatments also regulated transcription via significant differences in gene levels related to apoptosis and cell cycle progression. The data collected demonstrate some of the physiological effects of EL and ED on the cellular and molecular level. -

PrR1 is highly expressed in lignified inflorescence stem tissue, whereas PrR2 expression is barely detect- Keywords: able in stems.

Chemical Structures of Lignans and Neolignans Isolated from Lauraceae

Academic Editor: David Barker Received: 09 November 2018; Accepted: 29 November 2018; Published: 30 November 2018 Abstract: Lauraceae is a good source of lignans and neolignans, which are the most chemotaxonomic characteristics of many species of the family. This review describes 270 naturally occurring lignans and neolignans isolated from Lauraceae. Keywords: lignans; neolignans; Lauraceae; chemical components; chemical structures 1. Introduction Lignans are widely distributed in the plant kingdom, and show diverse pharmacological properties and a great number of structural possibilities. The Lauraceae family, especially the genera of Machilus, Ocotea, and Nectandra, is a rich source of lignans and neolignans, and neolignans represent potential chemotaxonomic significance in the study of the Lauraceae. Lignans and neolignans are dimers of phenylpropane, and conventionally classified into three classes: lignans, neolignans, and oxyneolignans, based on the character of the C–C bond and oxygen bridge joining the two typical phenyl propane units that make up their general structures [1]. Usually, lignans show dimeric structures formed by a β,β’-linkage (8,8’-linkage) between two phenylpropanes units. Meanwhile, the two phenylpropanes units are connected through a carbon–carbon bond, except for the 8,8’-linkage, which gives rise to neolignans. -

Rodríguez, Javier Espino * and María Garrido * Neuroimmunophysiology and Chrononutrition Research Group, Department of Physiology, Faculty of Science, University of Extremadura, 06006 Badajoz, Spain; [email protected] (P.C.); [email protected] (A.B.R.) * Correspondence: [email protected] (J.E.); [email protected] (M.G.); Tel.: +34-92-428-9796 (J.E. & M.G.) Received: 22 October 2020; Accepted: 7 December 2020; Published: 12 December 2020 Abstract: Phenolic compounds are secondary metabolites widely spread throughout the plant kingdom that can be categorized as flavonoids and non-flavonoids. Interest in phenolic compounds has dramatically increased during the last decade due to their biological effects and promising therapeutic applications. In this review, we discuss the importance of phenolic compounds’ bioavailability to accomplish their physiological functions, and highlight main factors affecting such parameter throughout metabolism of phenolics, from absorption to excretion. Besides, we give an updated overview of the health benefits of phenolic compounds, which are mainly linked to both their direct (e.g., free-radical scavenging ability) and indirect (e.g., by stimulating activity of antioxidant enzymes) antioxidant properties. Such antioxidant actions reportedly help them to prevent chronic and oxidative stress-related disorders such as cancer, cardiovascular and neurodegenerative diseases, among others. Last, we comment on development of cutting-edge delivery systems intended to improve bioavailability and enhance stability of phenolic compounds in the human body. Keywords: antioxidant activity; bioavailability; flavonoids; health benefits; phenolic compounds 1. Introduction Phenolic compounds are secondary metabolites widely spread throughout the plant kingdom with around 8000 different phenolic structures [1]. -
